Two notions of scalarity of discourse relations are distinguished: qualitative and structural scalarity. While qualitative scalarity is a well-studied phenomenon, structural scalarity is introduced as a syntactic notion. Some semantic properties in terms of informativity are pointed out. Drawing on existing work in Optimality Theory and Game Theory, structural scalarity is given a qualitative interpretation, tying the two notions together again.
